SOlve the system of equations using substitution

y=2x-10

y=4x-8

It should be,

4x-8=2x-10 because you substitute that for y.

Now you do,

4x-2x because you do the opposite of the positive 2x as you bring it to the other side.

That is,

2x-8=10 now you bring the 8 to the other side.

2x=10+8 I added it because I do the opposite and it is a negative 8 so I add.

2x+18 now divide

x=9 that's the answer.
